API Std 650 welded steel storage tanks heat-affected zone

API Std 650 welded steel storage tanks weld tightness test: remove dirt from the API Std 650 welded steel storage tanks weld, apply white powder emulsion, spray kerosene on the other side of the weld after drying. Because of the strong penetration of kerosene, if kerosene is sprayed after 12 hours (under low temperature conditions, the time can be extended), if the surface of the welded seam coated with white emulsion has no spots, the welded seam meets the requirements.

Density of API Std 650 welded steel storage tanks Liquid Stored
The density of the liquid stored shall be its maximum density within the range of design temperatures, but no less than 29.3 lbf/ft3 for methane, 34.21 lbf/ft3 for ethane, and 35.5 lbf/ft3 for ethylene.
Design Metal Temperature
The design metal temperature of each component exposed to the liquid or vapor being stored shall be the lower of the temperatures specified as follows: The design metal temperature of the components of the API 620 single-wall tank or the inner tank of a double-wall tank shall be the minimum temperature to which the tank contents shall be refrigerated, including the effect of subcolony at reduced pressure."

API 650 petroleum storage tank stipulates that if the thickness of the lower siding obtained by calculating the anti-overturning moment is greater than the thickness of the API Std 650 welded steel storage tanks hydrostatic pressure test (both do not include the corrosion margin), the calculated thickness of the above siding required by the hydrostatic pressure is It should also be increased by the same proportion, unless special analysis is performed to determine the seismic overturning moment and corresponding stress at the bottom of each layer of API 650 petroleum storage tank wall.
